Bayu Marhaenjati – Police disclosed on Friday that members of the Indonesian Navy were allegedly involved in a string of motorcycle gang attacks in Jakarta that left two civilians dead and over a dozen others injured during the past week.

Jakarta Police spokesman Sr. Comr. Rikwanto said the Navy Police, better known as Pomal, had agreed to cooperate with his office to handle the case.

"Based on testimonies from witnesses, [Navy members] were allegedly involved [in the motorcycle gang attacks]. That is why we are now cooperating with a team from Pomal to investigate this," Rikwanto said in Jakarta on Friday.

"Pomal and Jakarta Police will conduct joint patrols to prevent [other attacks] and search the perpetrators. We'll take firm action against any officers found involved [in the attacks]."

On Saturday of last week, one person was killed and three others were injured near Lake Sunter in North Jakarta, reportedly attacked by a motorcycle gang. The next day, five people were injured in another biker gang attack in Kemayoran, Central Jakarta.

On early Friday morning, a biker gang launched attacks in three different areas, namely Tanjung Priok in North Jakarta and Kemayoran and Salemba in Central Jakarta, leading to the death of one person. At least seven others were injured.

Police allege that the five attacks were committed by the same group in retaliation for the killing of Arifin Sirih, 25, a Navy member. Arfin was killed in an attack by a motorcycle gang in Pademangan Timur, North Jakarta, on March 31. (BeritaSatu/JG)
